To all whom it may concern:

Be it known that I, MILroN C. Arrnnenrn, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Liners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to liners for molds of type casting machines, the liner forming the end of the mold by which the length of slug cast is determined.

In the casting of slugs for type or lines of type, it is necessary to vary the length of the mold space for slugs of different length. That is to say, where a line of type of one length is set and it is desired to change over to set a line of type of less length or greater length, it is necessary to change the liner so as to shorten or lengthen the mold space. It is customary, in the usual type of ma chine now used, to funish a set of liners which are fractional in sizes, providing for all the various lengths of slugs to be cast. Obviously the number of liners which it is necessary to keep on hand is very considerable, and it consumes time also for the operator to actually remove the one liner from the machine and select the proper liner to replace in the machine. Furthermore, the unnecessary actual removal of the liner is objectionable because the liner is likely to become misplaced or lost.

The objects of the invention are to overcome the disadvantages of the usual type or liner; to provide a single liner which will permit casting slugs of different length; to obtain accuracy in setting the liner so slugs of different length will be properly cast; to permit each successive point of slugs to be cast; to adapt the device to machines now in use; to avoid complicated structure and multiplicity of parts; to secure simplicity of construction and use; and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawing in which like numerals of reference indicate similar parts through the several views;

Figure l is a perspective view of a portion of a mold showing my invention applied thereto;

F igure 2 is a longitudinal section through the liner and a portion of the mold;

Figure '3 is a plan or face view of the liner; and

Figure 4 is a view similar to Figure 3 showing a supplemental liner.

In the specific embodiment of the invention illustrated in said drawing, the referenc'c numeral 1 designates in general the mold, which includes as a part thereof a mold disc 2 having gear teeth 3 on its periphery by means of which said mold disc is rotated as occasion requires. From the front of the mold 1 projects a base 4 at one end of which is adapted to be laid a stationary liner 5 and at the other end of which is laid the adjustable liner 6 in which the present invention inheres more particularly. A cap 7 is then applied on top of the two liners 5 and 6, being held in place by suitable means such as the bolts 8. It will accordingly be observed that a mold opening 9 is thus provided bounded by the base 4' and cap 7 011 its longitudinal faces and bounded at itsends by the end edges of the fixed and adjustable liners 5 and 6.

In the operation of setting up type in a machine of this character it becomes necessary to set up type of one length of lines and thereafter set up type of another length of lines. To do this the length of the mold space has to be'changed. According to the present invention, changing of the length of this mold space is obtained by moving the adjustable liner in or out, that is, toward or away from the fixed liner 5.

In order to prevent the liner from sliding from position, it is customary to provide a pin 10 projecting from the mold base i for a height substantially qua-l to the thickness of the liner 6. This pin will therefore not interfere with proper seating of the cap 7 upon the liner, but will form positive means for holding the liner against transverse movement. The pin is preferably offset with respect to the centre line of the liner, and is adapted to enter one of a plurality of holes 11 provided in said liner. As may clearly be seen in Figure 3, two rows of holes are provided. One row represents change in position oi the liner of whole points. In other words, if the pin 10 is inserted in the end hole of the liner and later the liner is moved so the pin is positioned in the next hole in the same row, the liner will have been moved a whole point. The holes 11 of the other row are staggered with respect to the holes of the first mentioned row. Thus when the liner is moved so the pin changes position from the end hole of one row to the adjacent end hole of the other row, the liner has been moved a half point. In this manner the liner is adapted to be utilized for molding any length of line within the range determined by the extreme end holes of the two rows. It will be appreciated, by those skilled in the art, that to insert the pin in any hole of one row, the liner will be positioned one side up whereas to position the pin in a hole of the other row the liner will be turned over or positioned the other side up.

The liner as shown, is provided with a slot 12 open at one end of the liner for ac commodation of the bolt 8, and as shown 1n Figure 1, the portions 13 on either ide of the slot 12 may project downwardly past the bolt. The liner as thus constructed, therefore requires no alteration in the construction or arrangement of the machine but will Simplify the use of the machine and increase the eliiciency of the operator and decrease the time consumed in making changes from one length of slug to another.

Where it is desired to provide for a shorter length of slug than may be obtained from the liner above described, a supplementary liner 14 may be provided similar to the one already described, but of greater length so as to fill more of the opening 9 in the ma-- chine. This supplementary liner illustrated in Figure 4 is provided with holes 11 in two rows as above described and also has a slot 12 with portions 13, 13of the liner on opposite sides of the slot. The holes 11 bearthe same relation to the slot 12 in this supplemental liner as they bear to the slot 12 in the primary structure described above and shown in Figure 3. The additional length of the supplementary liner is at the opposite end of the same from the slot, and the extent of this additional length or extension, designated bynumeral 15 may be varied as found necessary or desirable.

Obviously detail changes and modifications may be made in the manufacture and,

1. A liner for the purpose specified in cluding a body portion having a plurality of holes in staggered relation whereby the said liner may be shifted from one position to another and positively held in position.

2. A liner for the purpose specified including a body portion having holes arranged in rows longitudinally of said body portion whereby the said liner may be, shifted from one position to another and positively held in position.

3. A liner for the purpose specified includ ing a body portion having holes arranged in rows longitudinally of said body portion, the holes of adjacent rows being staggered with respect to each other whereby the'said liner may be shifted from one position to another and positively held in position.

4. In a linotype machine, the combination with a base and cap, of a liner adapted to be included between said base and cap, said base having a pin projecting therefrom for entry in the liner, and said liner having a plurality of holes arranged in rows longitudinally of said liner for reception of said pin whereby the liner may be shifted by inserting the pin in a different hole.

5. In a linotype machine, the combination with a base and cap, of a liner adapted to be included between said base and cap, said base having a pin projecting therefrom for entry in the liner, and'said liner having a plurality of holes arranged in staggered relation for reception of said pin whereby the liner may be shifted by inserting the pin in a different hole, said cap and liner having longitudinal slots at one end, and a bolt adapted to enter said slots for clamping the parts together. s

Intestimony-whereof I affix my signature.
